SCREEN.

Specification of Letters Patent. Patented F61). 24:, 1920.

Application filed July 15, 1919. Serial No. 310,920.

To all whom it may concern:

Be it known that I, ELIZABETH LYNCH, a. citizen of the United Statesresiding at Minneapolis, in the county of ennepin and State ofMinnesota, have invented new and useful Improvements in Screens, ofwhich the following is a specification.

The object of my present invention is the provision of a window or doorscreen, designed more particularly as a specific improvement upon thescreen constituting the subject of my LettersPatent No. 1,109,437 ofSeptember 1, 1914, and inwhich the upper end of the screen cloth isconnected to the frame'without impairing the capacity of the screen inpermitting flies to pass out of a room.

To the attainment of the foregoing, the

invention consists in the screen construction hereinafter described anddefinitely claimed.

In the accompanying drawings, hereby.

by the lines 2-2, 33 and 4-4, respec-' tively, of Fig. 1.

Fig. 5 is a horizontal transverse section taken in the plane indicatedby the line 5-5 of Fig. 1, looking downwardly.

Similar numerals of reference designate corresponding parts inall of theviews of the drawings.

The lower cross-bar 1 and the side bars 2 of the screen frame may be andpreferably are of the ordinary well known construction, and the sameistrue of the'lower molding strip 3, the side molding strips 4 and themajor portion of the screen cloth 5.

In furtherance of my invention the upper cross-bar 6 of the screen frameis provided at points intermediate of its transverse center and its endswith recesses 7 the walls 8 of which are inclined inwardly from theouter side of the frame bar 6 to the lower edge of said frame bar wherea substantial edge point 9 is left for an important purpose hereinafterset forth. The provision of the said recesses 7, located as stated,leaves the upper bar 6 with an intermediate portion 10 and 11 of theupper bar 6. The said cutting of the upper portion of the screen clothaffords screen ledges 15, and these ledges 15 are strongly secured tothe lower edge of the upper bar 6, as shown. In the said ledges 15 areprovided openings 16 through which flies may pass and thereby escapefrom the room, that is guarded by my novel screen.

It will be apparent from the foregoing that my improved screenconstruction may be embodied either in a window screen or in a screendoor, in the discretion of the manufacturer; also, that by virtue of theconstruction specifically set forth, the connection of the upper portionof the screen cloth to the upper bar 6 of the frame is rendered strongand durable without impairing the capacity of the screen in permittingthe outward passageof the flies.

Having described my invention, what I claim and desire to secure byLetters-Patent, is: I

A screen comprismg a frame the upper bar of which is provided at itsouter side with intermediate recesses arranged at points between itstransverse central port1on and 1ts end portlons, a screen cloth theupper portion of which is cut and'has upward extensions, in the sameplane as its major portion, and secured against the outer sides'of thesaid transverse central and end portions of the upper bar and'also hasbetween said upward extensions ledges extending inwardly at substantialright angles to 7 its major portion and below the said recesses andsecured to the lower edge of the upper bar, and escape openings in saidledges.

In testimony whereof I afiix my signature.

' ELIZABETH LYNCH.
